The object of this invention is to facilitate the harvesting ofpotatoes.

The invention consists in the peculiar c011- struetiou and arrangementof parts, as hereinafter fully described, and pointed out in the claims.

A represents the plo'w-beam, to the forward end of which are secured bythe bolts B O the arms of the clevis D. Theends of the arms of tl: eclevis D, in the rear of the bolt B, are widened vertically, and havecurved rows of holes formed in them, to receive the rear bolt, 0, sothat the plows can be adjusted at any desired pitch by moving the bolt 0from one to another of the said bolt-holes, the bolt B serving as apivot in making the adjustment. The forward end of the clevis D is bentupward and has a number of holes formed in it to receive the draft, sothat the point of draft attachment can be raised and lowered to causethe plows to work deeper or shallower in the ground, as the depth of thepotatoes may require.

In bearings in the forward part of the arms of the clevis D revolves anaxle, E, upon the ends of which are placed the wheels F. Upon the innerend of the hubs of the wheels F are clutch-teeth G, to engage with theteeth ofthe clutches H, to cause the said wheels to carry the said axlewith them in their revolution. The clutches H are held outward againstthe hubs of the wheels F by spiral springs I, placed upon the axle E,between the said clutches H and the clevis D.

To the under side of the middle part of the beam A is attached across-bar, J, the lower side of which is grooved to receive thehorizontal upper parts of the standards K. The arms of the cross-bar Jare slotted longitudinally to receive the bolts L, that secure thestandards K in place, so that the said standards K canbe readilyadjusted to move the plows M, attached to the lower ends of the saidstandards, toward or from each other, as may be required. The outerparts of the standards K are bent downward to bring the plows M intoproper working positions.

To the rear end of the plow-beam .A is attached a cross-bar N, to theends of which, or to connecting-plates 0, attached to the said ends, arebolted or otherwise secured the upwardly-projecting side arms of theplow P, so that the said plow will be drawn from the plow-beam A.Theplow P is made angular in plan view, is concaved upon its rear edge,is slightly concaved upon its upper side, between i ts center and ends,and has its upper side smooth, so that it will readily pass through thesoil. The plows M P are made with separable points, so that the saidpoints can be readily removed when worn and replaced with new points.

To the under side of the rear edge of the plow P are hinged, by bolts orother suitable means, the forward ends of a number of rods, Q, the rearparts of which pass through eyes attached to the bar It, or areotherwise loosely connected with the said bar It, so that the rods Qwill be securely supported and the rods and bar will have a free lateralmovement. The middle part of the bar It is slightly concaved, and itsend parts are bent upward into vertical positions and have short chainsS attached to them. The upper ends of the chains S are attached to therear ends of arms T, the forward ends of which are attached to the endparts of the cross-bar N, so that the cross-bar R and the rods Q willbesupported in such a manner as to allow them to have a free lateralvibration. The rods Q are curved upward, downward, and rearward, andproject in the rear of the cross-bar R, which shape causes them toseparate the potatoes more thoroughly from the soil as the potatoes andsoil pass back along the said rods, while the concavity of the bar Rcollects the potatoes into the middle part of the rear end of the shakeras they pass off the said shaker. \Vith this construction, as themachine is drawn forward, the plows M throw the soil from the sides ofthe hills, while the plow P passes beneath and raises the potatoes andthe soil in which they are embedded, and the shaker separates thepotatoes and soil and delivers the potatoes at the rear end of the saidshaker, the said soil falling through the shaker to the ground. The plow1? is further strengthened against the draft-strain by the rods U, therear ends of which are attached to the lower parts of the upright armsof the said plow I The forward ends of the rods U are secured to thebeam A by the clevis-bolt B or other suitable means. I

To the axle E, between the arms of the clevis D, is attached agear-wheel, V, the teeth of which mesh into the teeth of a smallergearwheel, WV, pivoted to projections formed upon the upper edges of thearms of the elevis 1).

To one of the journals of the gear-whcel \V .is attached a era-11k, X,to which is pivoted the forward end of the connecting-rod Y. The rearend of the connecting-rod Y is pivoted to the crank Z, formed upon orattached to the upper end of the vertical shaft (1, which rocks inbearings attached to the end of the cross-beam N or the plate 0, and theupright arm of the plow P.

e To the lower end of the shaft/a is attached a crank-arm, b, the rearend of which is connected with the upward]y-proiecting end of thecross-bar It. By this construction the shaker will be vibratedlaterally, to remove the soil from the potatoes, by the advance of themachine.

To the center of the crossbar Nis attached the lower end of an uprightbar, 0, which passes up through a slot in the rear end of the tongue d.The tongue (1 is attached to the forward part of the frame 0, to theside bars of which are attached bearings in which revolves the axle f ofthe wheels 9.

Upon the inner ends of the hubs of the wheels 9 are formed clutch-teethh, with which engage the teeth of the clutches i, sliding upon the axlef, and held out against the wheels 9 by spiral springs j, placed uponthe axle f, between the clutches i and the side bars of the frame 0, sothat the machine can be backed without operating the mechanism, and sothat one of the wheels 9 can run slower than the other, or even beturned back in turning and in following crooked rows without stoppingthe proper operation of the mechanism.

To one of the clutches z is attached a large gear-wheel, 7c, the teethof which mesh into the teeth of the small gear-wheel Z, attached to theend of the shaft m. To the shaft m', between the side bars of the frame6, is attached in Fig. 2, so as to take the potatoes from the rear partsof the shaker-rods Q, or from the ground, and carry them over the saiddrum.

To the ends of the drum n are attached vflanges p, to prevent thepotatoes from escaping at the ends of the said drum. The j ournals oftheshaft m revolve in hearings in the rear ends of the levers g, whichride upon the axle f, and are fulcrumed at their middle parts to thesaid axle f at the inner sides of the side bars of the frame 0. Thelevers q are held parallel with each other while supporting the drum n,and are made to move together, when raising and lowering the said drum,by crossbars r, attached to them a little in the rear of theirfulcrum-points and at their forward ends, as shown in Figs. 1 and 2. Thelevers q, and with them the drum n, are held in any position into whichthey may be adjusted by two catch-levers, s, pivoted to the forwardcorners of the frame 0, and which engage with the forward crossbar r ofthe said levers. The rear edges of the catch-levers s are toothed toengage with the forward edge of the cross-bar r, and are held againstthe said cross-bar by spiral springs i, attached to their upper parts,and to a cross-bar of the frame 0. With this construction the driver,while sitting upon the seat u, can adjust the picking-drum a by pushingthe levers 8 forward with his hands and operating the levers q with hisfeet placed upon the forward cross-bar r. The drivers seat a is attachedto the upper end of the spring-standard '1), the lower end of which isattached to the forward crossbar of the frame 0.

Upon the rear, ends of the levers q are formed upwardly-projeeting arms10, which are strengthened in position by the inclined braces 00, and tothe upper ends of which is journaled the shaft y.

To the shaft y is attached a cylinder, 2,

and is provided with rows of rearwardlycurved teeth 1, arranged to passbetween the teeth 0 of the drum n, and clear the said teeth 0 of anyvines or weeds that may be carried up by them.

To one of the journals of the shaft 3 is attached a pulley, 2, aroundwhich passes a belt, 3, which is crossed, and passes around a largerpulley, 4, attached to the end of the shaft m, so that the cylinder zwill be driven from the drum 12, but in the opposite direction.

To the rear ends of the side bars of the frame 0 are attached the upperends of bars or straps 5, the lower parts of which are inclined to therearward, and to them is attached a box, 6, to receive the potatoes. Tothe upper edge of the forward side of the box 6 are attached teeth orwhich is placed directly above the'drum n,

hopper-shaped, and is provided with an opening in its lowestpart, whichis closed by a door, 8, which is hinged at its forward edge to the loweredge of the forward side of the said box, and is held closed-by a cord,9, attached to its rear edge. The cord 9 passes through staples or otherguides attached to the rear side of the box 6, and extends forward intosuch aposition that it can be readily operated by the driver said point.

from his seat to release the door 8 and allow the potatoes to drop tothe ground in a heap.

To the forward part of the clevis D is attached the end of a cord, 10,which passes over a pulley, 11, pivoted to the tongue (I or to a supportattached to the said tongue. The other end of the cord 10 is attached tothe lower end of a lever, 12, which is pivoted at a little distance fromits lower end in a slot in the tongue d.

To the rear part of the plow-beam A is attached the end of a cord, 13,which passes through a slot in the tongue d over a guidepulley, 14,pivotedto a support attached to the said tongue d, and its other end isattached to the lever 12 at the same distance above its pivoting-pointthat the cord 10 is below the WVith this construction, by moving theupper end of the lever 12 forward, the front and rear parts of the plowmechanism will be raised from the ground at the same time.

Having thus described my invention, I claim 7 as new and desire tosecure by Letters Patent- 1. I11 a potato digger and picker, thecombination, with the plow P, of the bar R, suspended from the rear ofthe plowbean1, the
